Note collective

Input Parameters

dm - The DM
dmAux - The related auxiliary DM
p - The point in the original DM

Output Parameter

subp -The point in the auxiliary DM

Notes: If the DM is a submesh, we assume the dmAux is as well and just return the point. If only dmAux is a submesh, then we map the point back to the original space.
